I'm in the very same situation. And about to run out of Stephen King books at my local library.. These questions may help you, as my answer to a more thrilling life lies within them as well:

Did you have a life that was lost, and want to regain it?
Do you have dreams of how life ideally should be?
Or, do you merely have an impulse to try something new.. ?

Try exploring these! Do they ring any bells for you?
